274 ANNALS NEW YORK ACADE3IY OF SCIENCES 



SECTION OF GEOLOGY AND MINERALOGY 

 3 March, 1913 



Section was called to order at 8 :20 p. m., Vice-President J. E. Wood- 

 man presiding. 



The minutes of the previous meeting were read and approved. 



Vice-President Woodman called President McMillin to the chair, and 

 the following programme was then offered : 



J. E. Woodman, The Inteebedded Iron Ores of Nova Scotia. 



Summary of Paper 



Professor Woodman elaborately illustrated the field evidence by lan- 

 tern views and hand specimens, some half a hundred of each. The net 

 results seemed fairly to warrant a modified form of the replacement 

 theory as an explanation of these deposits. 



Professor Kemp commented upon the new evidence in the light of the 

 interesting body of data which seemed to argue somewhat in opposition 

 to the findings of Professor Woodman, as presented by workers in other 

 regions, and concluded with an invitation for remarks by Professor Van 

 Ingen, of Princeton University, a former officer of the New York Acad- 

 emy of Sciences. Professor Van In'GEN stated that the results of his 

 investigations into the iron-ore deposits of Newfoundland were as yet 

 inhibitive, but that he had found extremely probable evidence of Paleo- 

 zoic faunal connection between Newfoundland and certain European 

 localities. 

 . The Section then adjourned. 



Charles T. Kirk, 



Secretary.
